Best of the Test: Top Dishwashing Detergents to Get Your Plates Spotless

Of the powders, tabs, and liquid formulas we tested, these did the best job of completely cleaning stuck-on and baked-on messes. We looked at performance on the normal- and heavy-duty cycles, as well as spotting, filming, and hard water residue on glasses.

Great Value Dishwashing Detergent

At only 10 cents per load, Wal-mart's Great Value Dishwashing Detergent was one of the least expensive formulations we tested and turned out to be our best-in-test powder. Great at removing even the most baked-on food, this powder detergent also minimized hard water spotting on glasses and left the remaining items in our load completely spotless. This formula did noticeably better than most others in our test at clearing lipstick stains from our coffee cups.
